Don’t you just love bugs?

Steps to reproduce:

1. open Internet Explorer 7
2. go to any page (required only if blank page opens when IE7 starts)
3. press Ctrl+ (increases size of text and images)
4. open another tab
5. go back to first tab
6. text is scrambled

Not reproducible every time, try it several times, and it should reproduce.

What is the chance of visiting a page that has a certificate that has expired nine minutes ago?

There was important security update of WordPress recently. In upgrade instructions it is suggested to delete old files on the server, and then upload new files, and I did as they suggested.

A few days ago I wanted to upload an image and got this error message.

The uploaded file could not be moved to [...]/wp-content/uploads/[...].
Warning: Cannot modify header information – headers already sent by (output started at [...]/wp-admin/admin-functions.php:1879) in [...]/wp-includes/functions.php on line 1219

I searched for that error message, but did not find anything useful. I looked at source files mentioned, but I am not very familiar with PHP, so no luck there too.

Then I remembered that I had problems previously after upgrading because WordPress did not have permission to write to upload folder. I checked it and yes, that was the problem. I fixed permissions and upload worked again.

I am just surprised how error message did not say that WordPress does not have permission to write to a folder, but something about headers. I thought that not having permission is one of the common scenarios.
